Transom Window

A transom window is a type of window that typically spans the top of a door. Transom windows are often found in older buildings where they were used for natural ventilation, but they can also be found in newer construction

The term transom window comes from the word transom, which means ‘a cross beam lying over the top of a door or window’ (derived from the Latin words trans meaning “across” and sumere meaning “to take”).

A transom window is typically one that spans across the top of an exterior door or window; sometimes, interior doors or windows are also fitted with this type of window.

It is worth noting that in some cases, the term ‘transom’ is also applied to a window that spans across a ceiling, or a window that spans across a larger opening, such as a transom over the door leading from the dining room to the kitchen.

In most cases, transom windows are installed near the top of exterior doors for decorative effect.

In older homes with wide hallways and high ceilings, they were put in place to allow ventilation. In these situations, transoms were often installed above interior doors as well as exterior ones.

As mentioned, the transom window, which is usually situated over the front entrance or another window, provides a decorative purpose to bring character to your home.

They are available in a variety of window designs, such as a row of small transparent squares or a semi-circle created by numerous triangular slices.

By providing a focal point over the main door of the property, this design may improve curb appeal.

They may also be used to add elegance to interior walls and to convey light from one area to another.

The price varies greatly based on the operation and size of the window. A non-operable transom window, on the other hand, will set you back at least $150.

A window with one-of-a-kind ornamental accents and that opens will raise the price.
